gzdoom/src/g_hexen/a_serpent.cpp
Randy Heit aef34f9aa5 - Removed xlat_parser.h from the repository. Lemon was always being run on
xlat_parser.y because both files had the same time stamp after an update,
  and Lemon only rewrites the header file if it's changed.
- Added $volume SNDINFO command. This is multiplied with the volume the sound
  is played at to arrive at the final volume (before distance attenuation).
- Added the CHAN_AREA flag to disable 3D panning within the min distance of a
  sound. Sector sound sequences (except doors) use this flag.
- Added the CHAN_LOOP flag to replace the S_Looped* sound functions.
- Restored the sound limiting.
